IMPROVEMENT iN MACHINES FOR` RWETING BUTTONS TO FABRICS.

Specification forming part of Letters Patent No. 132,537, dated October29, 1872.

To all whom it may concern:

Be it known that I, JOHN J. MERvEsP, of Brooklyn, county of King andState of New York, have invented certain Improvements in Machines forRiveting Buttons to Fabrics7 of which the following is a specification:

The invention consists in having one end of a spring fastened to theframe of a machine and the other end fastened to the die or plunger, inorder to press the die on the cloth or other material to be riveted, andto pre-' vent the rivet from bending or vibrating while a head is beingformed on it, in combination with a lever or lifter'for raising ordepressing' the punch or plunger, with a die formed with two or moredifferent faces, so as to suit different sizes of buttons or burrs, anda counter-sunk punch, o1', in some cases, a serrated or pointed one,according to the kind of work to be done, with a'hammer for striking thepunch or plunger.

Figure 1 is a perspective view of my machine with the die b secured tothe frame by a rivet passing through the slot c. Fig. 2 is a sideelevation of a modification of the same with part in section. Fig. 3 isa modification or the same, in which the die 'b acts as a plunger. Fig.4 is a modification ofthe same, with part in section, in which the punchm is operated by the lever z being struck by the plunger i". Fig. 5 is amodification of the plunger, die, punch, yand anvil, shown in Fig. 2.Fig. 6 is a modilcation of the die shown at b, Fig. 2. Fig. 7 is amodification of the same used for riveting on alevel surface, such asplain washers, bnrrs, 8vo. Fig. 8 is a modification of the same withspiral spring between the different faces of the dies. Fig. 9 is amodification of the same with four different faces. Fig. 10 is amodification ofthe die view of the punches, shown atm mim m, Figs. 1, 2,3, and 4,; and Fig. 12 shows a modification of the die, shown at b, Fig.1, with four different faces.

In Fig. 1, A is the frame of the machine; b, the reversible die, withtwo different faces, (modications of which are shown in Figs. 10 and12,) fastened in the frame by a bolt or pin, c, passing through a holein the latter, and a slot in the die b, or a hole may bein the die, anda slot cut in the frame, or a be able to regulate the die to thediameter of the material to be riveted, so that it will lie level on thebutton or burr to be fastened. This die has two diiferent faces-one forlarge and one for small buttons. The modification shown in Fig. 12 hasfour different faces-one for small, one for medium, another for largebuttons, and the fourth face for riveting burrs, or anything with alevel surface, and is secured to the machine the same as the die b, thedifference being that it has two holes crossing each other in order toallow either of its faces to be used. When the die shown in Fig. 10 isused, the spring h is dispensed with, being partly composed of a springitself, which supplies the place of the spring h.' The loops-on itssides are for the reception of the lifterve. One end of the spring dfastened to the machine, and the other to the die b. The lever or liftere is fastened, at t', to the spring d. The latter holds the article tobe riveted firmly between the die I; and the anvil g, and prevents itvibrating or the rivet bending While being struck-by the hammer f.

When a button is to be riveted the hammerhandle f is raised up andpressed back, when it engages with the loop t ofthe lifter e, whichraises the die b, when the article to be riveted is placed under the dieand the hammer dropped on the punch m. In Fig. 2 the machineis shownwith the hammer raised up and bent backward. One end ofthe spring d isfastened to the machine, while the other end passes through a hole inthe plunger. The lever e passes through the loop t' of the spring d. The

other end of it is fastened to the hammerhandle. The end of the springh. passes through a hole in the side of the die b'. This arrangementkeeps the die in position and allows it to be reversed when required.

When a button or other article is to be riveted the handle is pressedback, as shown, when the levere raises the plunger and die, when thematerial to be riveted is placed under the die and the hammer dropped,as in Fig. 1. In Fig. 3the die b. acts as a plunger. It has a slot, p,cut in either end of it, through which one end of the spring d passes,and presses it toward the anvil y. The punch m passses through the die,and is kept in position by the spring h. This die is made with 'slot cutin both. The object of the slot is to 2 Y isms@ a large and small facefor different kinds of buttons. When it is to be reversed it is takenout of the arm after the spring d is slipped from the slot p, and turnedupside down when the spring d is put in the slot p. This machine isoperated the same as' that shown in Fig. 2, when a button is to beriveted. In Fig. 4 the plunger o is struck by a lever operated on its opposte end by a longer plunger, r, the end of which is provided with adetachable head, l, which can be removed when worn and replaced by'a newone. When a button or other article is to be riveted the handle israised up and pressed backward, when it engages with the loop t of thelever or lifter e, which raises the long plunger o" and depresses theplunger o and die b, when the article to be riveted is placed on the dieand the hammer dropped on the plunger. Either of the dies shown in Figs.6, 7 ,.8, or 9 may be used with this machine.

The die shown in Fig. 6 has two level faces, one large and one small,with a rim around each to keep the buttons in position while beingriveted; it also has a hole in its side for the reception of the springshown at h, Fig. 2.

The die shown in Fig. 7 is level on both faces, and is used when plainburrs or washers are to be riveted, as in shoes, harness, &c.

The die shown in Fig. 8 has two faces, a large and a small one, forsmall or large buttons, with a spring soldered or otherwise fastenedbetween them. This spring is coiled small in the center in order to iitthe punch tight and keep itself on it. When this die is used the springshown at h h is omitted.

The die shown in Fig. 9 is struck out of a piece of sheet metal withthree or four different faces, so that it can be used on different sizesof buttons, or its level face can be used in the riveting of plainburrs, as in harness, shoes, 85e.

Either of these dies shown in Figs. 6, 7. 8,

5, with its under die, Acan be used in place ot' the plunger, punch, anddie shown in Fig. 2. This modification will rivet a small solid wirerivet on both ends simultaneously. The punch j is kept in its place bythe wedge 7c, and can be removed by withdrawing it. The die u is held bytwo rivets upon which it works. The under die is held the same as' thetop one, and its punch fits into a hole in the anvil V. When worn it canbe punched out and replaced by a new one.

All the dies shown press on the button or burr before the punch touchesthe rivet. I prefer to use the dies shown in Figs. 8 and 9, as they aremade for less than a quarter. the cost ofthe dies shown in Fig. 6, andat b, Figs. 2 and 4.

I claim as my inventionl. A die formed with two different faces,connected by a spiral spring, as shown in Fig. 8, for the purposespecified.

2. I claim a die formed with four different mes, as shown in Fig. 9, forthe purpose speci- 3. I claim thedies shown in Figs. 10 and 12, for thepurpose specified.

4. I claim, in combination with the frame A, hammer f, spring d, andlifter e, shown in Fig. 1, the use of either of the dies shown in Figs.10 and 12, and at b, Fig. 1, with the use of a punch either countersunk,serrated, or

pointed, and with or without the spring h,

Fig. 1, substantially as specified.

- 5. I claim, in combination with the frame A, hammerf, spring d, levere, plunger o, Fig. 2, the use of either of the dies shown in Figs.

67, 8, and 9, and at b, Fig. 2, with the use ofV either of the punchesshown in Fig. 11, and

-with or without the spring h, Fig. 2, for the purpose described,substantially as speciiied. 6. I claim the combination of the springs dh, lifter e, punch m, die b, with hammer fand frame A, shown in Fig. 3,all constructed and operating substantially as described.

7 I claim the combination of the frame A, springs d h, lifter e, die b,countersunk punch m, plungers o o", head Zwith hammer f, all constructedand operating substantially as shown and described.

8. I claim the modification ofthe die, plunger, and punch, with itsunder die shown in Fig. 5, substantially as described.
